Water:

Two new wells, each 350 feet deep drawing groundwater from the Devonian (includes Cedar Valley Limestone) aquifer and the new water treatment plant were fully operational February of 2002.  The water treatment plant is rated at 400 gallons per minute.  Treatment consists of aeration, with iron and manganese removal from two sand filters.  Disinfecting is accomplished by chlorine gas; fluoride is added for dental hygiene and phosphate is added to prevent red water problems.  The city has one elevated storage tank with a capacity of 500,000 gallons.


The City of Northwood is a valid provider for new industry and business.  The water plant can produce 550,000 gallons per day of treated water with 500,000 gallons stored in the water tower.  Average use is 200,000 gallons per day; peak use is 300,000 gallons per day.


Wastewater:

The Northwood Wastewater Treatment Facility, constructed in 2018 is an activated sludge plant.  The Activated Sludge Process is an aerobic biological waste water treatment process that uses microorganisms, including bacteria, fungi, and protozoa, to speed up decomposition of organic matter requiring oxygen for treatment.  This process utilizes a multi-chamber reactor unit that uses microorganisms as a method to remove nutrients from the water. 


Garbage/Recycling:

The City of Northwood contracts with Northwood Sanitation for the pickup of residential garbage and recycling.  Garbage pickup is Monday only of each week, with special bags required.  The special bags can be purchased at City Hall, Northwood True Value, and Fast Stop Convenience Store.  Recycling pickups are the 1st and 3rd Wednesdays of each month, with special yellow or blue container required.  The container can be purchased at City Hall.
